Care & Repair
Brake Service
Spongy pedal? Grinding noise? We handle pad replacement, rotor resurfacing, fluid flushes, and complete brake system overhauls.
Oil Changes
Conventional, synthetic, and high-mileage blends — we use the right oil for your engine and inspect key components while you wait.
State Inspection
New York State safety and emissions inspection — quick, thorough, and conducted by certified technicians right here in Hewlett.
Suspension & Steering
Struggling with a rough ride or vague steering? We diagnose and repair shocks, struts, tie rods, and alignment issues.
Check Engine Light
Don't ignore that light. We read codes, trace root causes, and fix the real problem — not just clear the code and hope.
Why J-Mar
Built on Trust,
Built on Trust,
Not Transactions
We've seen what happens when customers walk into a shop and feel like they're walking into a trap. That's not us. We treat every car like it's our own and every customer like a neighbor — because most of them are.
Upfront Pricing
We explain the work, give you a clear estimate, and call before we do anything beyond the agreed scope.
No Surprises
If we find something else while working on your car, we tell you immediately — not after the bill.
Quality Parts
We use OEM or equivalent parts that meet manufacturer specifications — never cut-rate substitutes.
All Makes & Models
From economy compacts to heavy trucks, domestic or import — we have the tools and knowledge to handle it.
Our Story
A Neighborhood Shop
A Neighborhood Shop
That Stays
J-Mar Services Center has been a fixture on Broadway in Hewlett for years — not because we chase trends, but because we do the job right the first time. Our reputation isn't built on ads or discounts; it's built on repeat customers who bring their neighbors with them.
We know the difference between what your car needs and what a shop thinks it needs. That distinction is the foundation of everything we do. When you pull into our lot, you're not just another ticket number — you're someone's mom, someone's coworker, someone who just wants to get home safely.
What Customers Say
Word of Mouth
Word of Mouth
Speaks for Itself
I brought my car in for a check engine light and a suspicious noise. They diagnosed both problems in one visit, explained everything in plain English, and finished the same day. No upsell, no pressure — just honest work.
After a bad experience at a chain shop, I needed someone I could trust. J-Mar has been my go-to ever since. They've done brakes, an oil change, and a state inspection — all with the same straightforward, no-nonsense attitude.
Fair price, fair diagnosis, fair treatment. That's rare. They told me what needed attention and what could wait, and I've never felt like they were trying to pad the bill. My family uses them for all our vehicles now.
